Zastosowanie

Iodoacetamide has been used:
  • in protein digestion for proteomic analysis
  • to alkylate protein samples
  • in the denaturation of cow′s milk allergens, β-lactoglobulin (BLG) and α-lactalbumin (ALA)

Działania biochem./fizjol.

Iodoacetamide (IAA) is used to inhibit glycolysis due to its ability to irreversibly inhibit the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). IAA is used to investigate the role of cysteine residues in enzyme catalysis and the brain cell transport process. It can react with low molecular weight thiol compounds like mercaptoethanol and glutathione. IAN may also block enzymes like bromelain, cathepsin C, clostripain, and carboxypeptidase P.
Iodoacetamide acts as an alkylating reagent for cysteine residues in peptide sequencing. It is an irreversible inhibitor of enzymes with cysteine at the active site. It reacts much more slowly with histidine residues, but that activity is responsible for inhibiting ribonuclease.

Despite the common use of lipid-lowering medications, cardiovascular diseases continue to be a significant health concern. Atherosclerosis, one of the most frequent causes of cardiovascular morbidity, involves extensive inflammatory activity and remodeling of the vascular endothelium. This relentless inflammatory condition

mRNAs are regulated by nucleotide modifications that influence their cellular fate. Two of the most abundant modified nucleotides are N6-methyladenosine (m6A), found within mRNAs, and N6,2'-O-dimethyladenosine (m6Am), which is found at the first transcribed nucleotide. Distinguishing these modifications in mapping

Cysteines (Cys) made acidic by the protein environment are generally sensitive to pro-oxidant molecules. Glutathionylation is a post-translational modification that can occur by spontaneous reaction of reduced glutathione (GSH) with oxidized Cys as sulfenic acids (-SOH). The reverse reaction (deglutathionylation)
